Aquarium and Pond Care with EcoBio-Block

Once you have successfully built and set up your outdoor pond you may think that the hard part is over. While building your pond may indeed be the most difficult part of the process, you should also put a considerable amount of effort toward selecting the fish for your pond. You cannot simply go to the pet store and purchase a dozen feeder goldfish and expect them to thrive in your pond. There are only a few types of fish that are suited to living in outdoor ponds and each variety has certain requirements. Before you purchase the fish for your pond, perform some basic research to decide which type of pond fish is best for you and for your pond size.

Types of Pond Fish

Colorful koi

When it comes to outdoor ponds, koi are the most well-known species of ornamental fish used for stock. Koi come in a variety of shapes and colors including black, gold, red and orange. These fish look similar to goldfish but grow much larger and exhibit a wider variety of shapes in their fins and bodies. Because they grow to be quite large, koi require a pond capacity of at least 1000 gallons in order to thrive. These fish also require a variegated diet including fresh vegetables, fruit and specially formulated koi foods.

Goldfish come in a variety of shapes and colors which makes them a popular choice as a pond fish. Some of the most popular varieties of goldfish include Comets, Shubunkins and Orandas. Comets come in red, orange and white varieties – the calico varieties are called Shubunkin Comets. Orandas are a type of fancy goldfish known for the prominent hood that develops on top of its head.  In general, goldfish are a hearty species which does well in ponds with adequate filtration and aeration. Most goldfish prefer peaceful or slow-moving water and require a pond capacity of 250 gallons or more to thrive.

Precautions to Take with Pond Fish

Just as you should exercise caution when stocking your home aquarium, be careful when selecting the fish for your pond. Some species can grow very large or may become aggressive around other species. By doing some research before you purchase your pond fish you can prevent a disaster from happening later. Comets, for example, can be aggressive and should not be mixed with most other types of pond fish aside from koi. Goldfish and Orandas are generally peaceful species that can get along with a variety of species.

Tips for Keeping your Pond Healthy

A healthy pond requires routine maintenance in order to keep water quality high. Because goldfish and other pond fish are notoriously high producers of waste, adequate filtration is key to maintaining water quality. To give your pond a boost, consider installing one or more EcoBio-Block Waves. These blocks are infused with beneficial bacteria that multiply naturally to establish a colony in your pond. Once established, this colony of beneficial bacteria will help to break down organic waste products, remove odors and clarify cloudy pond water. While you should still maintain proper filtration and execute regular maintenance procedures, an EcoBio-Block Wave can help to keep your pond clean and healthy for your fish.

With the right landscaping and proper maintenance, even the most basic koi pond can be beautiful. However, if you really want your backyard pond to make a statement you should consider turning it into a water garden. Though it may sound like a complicated project, transforming your existing pond into a water garden can be as simple as adding a few potted aquatic plants. Not only will these plants enhance the appearance of your pond, but they will also benefit your koi and make your pond a healthier environment in which your fish can thrive.

Types of Pond Plants

When it comes to aquatic pond plants there are a variety of options which can generally be divided into four different groups. Oxygenators are the category of pond plants which grow entirely beneath the surface of the water where they help to increase the oxygen content and provide cover for your fish when they need it. Floating plants are those that do not need to be rooted in a pot or planter. These plants float on the surface, providing shade which helps to reduce algae growth in your pond.
Deep water pond plants like water lilies and lotus are largely ornamental. Some of these plants produce beautiful blooms which serve to add color to your water garden. The final category of pond plants includes bog plants such as cattails, grasses and reeds. These plants grow best in shallow areas and are most often used to blend the pond into the rest of the landscaping in your yard.

The Benefits of a Water Garden

The benefits of transforming your koi pond into a water garden extend far beyond the aesthetic. By adding live plants to your pond you will not only be making the pond a healthier environment for your fish but you also will be decreasing the necessary amount of maintenance as well. Aquatic plants use the waste produced by your fish as fertilizer and, in exchange, produce the oxygen your fish need in order to breathe. This is an extremely important benefit because koi require highly-oxygenated water in order to thrive. Live plants will also compete for nutrients with pond algae, thus reducing the amount of unsightly algae growing in your pond.

How to Add Plants to Your Pond

Before purchasing your pond plants, perform some basic research to decide what type of plants you want. As you research, determine what the potting requirements are for each type you have chosen. Fabric pots and plastic pots with no holes are the most common types of pots used in water gardens because they keep the potting soil contained and they can be moved easily. For those of your plants which need to be rooted, fill your pots with clay soil and anchor them with sand or gravel. Place the pots in the desired location within your pond, positioning your plants in the arrangement you find most attractive. Floating plants do not require pots – they can be left to drift along the surface of your water garden.

If you want to get the most out of your water garden, try adding a few EcoBio-Blocks to your pond. The EcoBio-Block nsM is a four-pack of water-clarifying stones made from natural zeolite and infused with beneficial bacteria. The special nitrifying bacteria infused in the EcoBio-Blocks will multiply rapidly once you have added the stones to your pond. These bacteria will clarify the water, remove odor and help to decrease the frequency of necessary pond maintenance. If the water in your koi pond is kept clean and clear, it will be a better environment for both your fish and your aquatic plants.

Algae growth can be a serious problem for both indoor aquariums and outdoor ponds. In an outdoor pond, a limited amount of algae can lend your pond a natural appearance and it can also provide a healthy food source for your fish. If algae spreads too quickly, however, and if its growth is not controlled it can threaten the healthy balance you have worked so hard to maintain in your pond. To avoid having to deal with a sudden algae problem, take early and consistent steps to control and limit algae growth within your pond.

The Pros and Cons of Algae in Ponds

Algae are single-celled organisms that thrive in warm, nutrient-rich water. In an outdoor pond, algae are an essential part of the food chain. Algae subsist on the waste produced by your fish and, in turn, become a food source for your fish. In limited quantities, algae can enhance the appearance of your pond by giving it a more natural look but if it grows out of control algae can cover the surfaces in your pond with a green or brown slime. In addition to this slimy muck, algae can also turn your pond water an unsightly shade of green. This may reduce the clarity of your pond water and make it more difficult for you to view your fish. In addition to the aesthetic problems induced by its growth, algae can also deplete the oxygen supply in your pond water which will make it a stressful environment for your fish.

Factors that Contribute to Algae Growth

Like any aquatic plant, algae require nutrients to grow and if your pond provides an abundance of these nutrients you may experience a problem with algae. Organic matter and uneaten fish food settle at the bottom of your pond which will, over time, result in a build-up of ammonia and nitrate on which algae can feed. Direct sunlight is another contributing factor in the growth of algae so if your pond is not shaded by trees you may have trouble with algae. Though it can be harmful to your pond if too much algae is allowed to grow, most ponds experience a “bloom” of algae in the spring. In most cases, your pond will find its balance after a few weeks and return to its normal clarity.

Tips for Controlling Algae

Installing an adequate filtration system in your pond is an easy way to limit the growth of algae. Many pond filters utilize chemical filtration which helps to remove the wastes and toxins that would otherwise provide a food source for algae. Adding aquatic plants to your pond is another easy solution because plants will compete with algae for the same nutrients, thus limiting the potential for algae to grow and spread.  Introducing some floating plants like water lilies may also help to control algae growth by cooling the water and providing shade.

In addition to these measures, adding an EcoBio-Block Wave or nsM to your outdoor pond can be effective in clarifying the water and reducing algae growth. EcoBio-Blocks are made from natural zeolite and special cement that has been infused with special beneficial bacteria. Once the block has been installed in your pond it will release bacteria regularly which will work to break down organic waste into ammonia, then nitrites and then into nitrates. EcoBio-Block keeps water healthy which discourages the growth of algae. It also appears to encourage the growth of anaerobic bacteria, which changes nitrates (on which bacteria feed) to nitrogen gas. This product is a simple way to control algae and a great way to keep your pond water clean and clear with no extra effort required on your part.

Filtration is one of the most important factors in determining whether your pond will be able to provide a healthy, balanced ecosystem for your fish. Not only do pond filters facilitate water flow which helps to reduce the growth of algae, but they also remove harmful toxins from the water and filter out waste to keep the pond water clear. Adequate filtration is particularly important in ponds where goldfish or koi are present because these fish produce a large amount of waste and require highly-oxygenated water. In order to ensure that your pond fish remain healthy, do some research before selecting a pond filter so you can be sure to purchase the type that is best for your particular pond.

Types of Pond Filter

Before you can begin to peruse your options in pond filters you need to decide between the two major types: external and submersed filters. External pond filters can be very large and are not installed directly in the pond. Because this type of filter is not housed within the pond itself it is much easier to clean and to change or add filter media when needed. Though external pond filters have the capacity to support larger biological loads than submersed filters, they can be unsightly and difficult to disguise.

Submersed pond filters are those which can be installed inside the pond itself. This feature allows you to easily conceal the filter from view using an arrangement of aquatic plants or decorative stones. A submersed pond filter can be filled with different types of filter media, as can an external filter, but this type is more difficult to clean because it must be removed from the pond first. Although submersed pond filters are limited in their ability to support large biological loads, they are extremely versatile and can be used for water features as well as basic pond filtration.

Tips for Selecting a Filter

After you have made your choice between an external and a submersed pond filter you need to select the right model for your particular pond. One of the most important factors in determining which filter is right for you is the size of your pond. Different filters are designed to support different biological loads. The model you choose should be able to filter one half of the total pond volume in an hour. If your pond is located in an area that receives a great deal of sunlight you may need a larger filter to counteract an increased rate of algae growth.

In addition to the size of your pond, the type of filtration you desire should also be a factor when making your decision. Mechanical filtration is the most basic function of a filter which involves removing solid waste from the water as it is drawn up through the filter media. Chemical filtration serves to remove toxins from the water and biological filtration involves maintaining a colony of beneficial bacteria which help to break down wastes and clarify the water.

Regardless of what type of filter you choose there are a few simple things you can do to keep your pond water clean and clear. Avoid overfeeding your fish and take steps to prevent your pond from becoming too crowded. You may also consider adding an EcoBio-Block Wave or EcoBio-Block nsM to your pond in order to facilitate the growth of a colony of nitrifying bacteria. EcoBio-Blocks are made from natural zeolite and infused with beneficial bacteria which will quickly multiply after being introduced into your pond. The presence of these bacteria will speed up the nitrogen cycle in your pond which will result in cleaner, clearer water and a healthier environment in which your fish can thrive.

Your pond filter is perhaps the most essential piece of equipment when it comes to keeping your pond clean and healthy. Pond filtration systems circulate the water to prevent algae formation, to remove waste build-up and they may also facilitate the growth of beneficial bacteria. Because filtration is key to the success of your outdoor pond, you should not buy a cheap one or purchase one too small for your pond. If saving money is a necessity, however, you can build your own pond filter from scratch.

Materials Needed:
Large plastic planter or stock tank
3-inch plastic shower drain
Jig saw
Joint compound
1 ½ inch PVC pipe
1 ½ to 1-1/4 inch threaded nipple reducer

DIY Pond Filter

The first thing you need in order to build your own pond filter is a large plastic planter or stock tank. Visit your local home improvement store to peruse your options. Next, trace around the plastic shower drain on the outside of the tank just below the rim. Cut out the hole with a jig saw, apply a bead of joint compound around the outside of the hole then insert the shower drain and press it firmly against the side of the tank to create a seal.

Measure across the bottom of the tank and divide the measurement by two. Cut two pieces of 1 ½-inch PVC pipe to 2 inches shorter than the measurement you just took and attach a PVC elbow to one end of each pipe. Connect the two pipes in the middle with a tee connector and insert a piece of PVC equal to the height of the tank vertically into the remaining connection on the tee. Top the vertical pipe with a 1-1/2 to 1-1/4-inch threaded nipple reducer then place the assemblage of pipes in the center of the planter or stock tank so the horizontal pipes rest on the bottom.

Position the elbows on the horizontal pipes so they point in opposite directions – this will create a swirling effect at the bottom of the tank which will increase the efficiency of the filtration. Cut a piece of rigid plastic mesh to the size of the stock tank or, if you are using a plastic planter, purchase a plastic sieve large enough to fit inside. Cut a hole in the middle large enough to pass the vertical PVC pipe through. The mesh should sit several inches above the bottom of the tank – elevate it with wooden blocks if necessary.

Fill the tank with your preferred filter media. You can purchase filter sponges from your local pet supply store, but regular dishwashing sponges and scrubber pads cost less and work just as well. These materials are ideal for use in pond filters because the pores catch unwanted waste and debris while also providing a place for beneficial bacteria to grow. Finish up your homemade pond filter by positioning it on the opposite end of the pond as your sump pump. Insert the hose from your sump pump into the 1-1/4-inch threaded nipple in the vertical piece of PVC and turn on the pump. The water will pass through the PVC pipes, swirl around the bottom of the tank up through the filter media and exit via the shower drain in the side of the tank back into the pond.

To turn your homemade filter into a more efficient biological filter, consider adding an EcoBio-Block Wave in addition to the sponges. EcoBio-Block products are infused with beneficial bacteria which naturally clear cloudy pond water, keeping it safe and healthy for fish. The EcoBio-Block Wave lasts for three years and can accommodate between 300 and 1000 gallons of water which means that it will keep working long after it becomes necessary to replace your other filter media. You can also install EcoBio-Block Waves along the bottom of your pond, instead of inside the filter, to clarify water and remove odors.
